Outline of Final Research Achievements

A logical control approach for continuous domain dynamical systems is developed in this research. First, a method to model a dynamical system in continuous domain as logical transient system is proposed that presents a mathematical representation of continuous system with logical variables and transient probability matrix. Then, optimal control problem with respect to logical variable cost function is solved by algebraic iterative algorithm. The solution is also extended to the systems involving stochastic behavior. Moreover, the proposed logical control approach is applied to residual gas fraction control of combustion engine and hybrid electric vehicle as benchmark practical control examples. Experimental validation conducted on full-scaled engine testbench is demonstrated.
